SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0633 PM CST Tue Nov 04 2025 Valid 050100Z - 051200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few lightning flashes may still occur early tomorrow morning along the California and Oregon coasts as low-topped storms approach the shoreline. Organized severe storms are not expected. ...Synopsis... A mid-level trough continues to approach the West Coast as an upper ridge tracks over the northern Rockies and mainly zonal flow aloft persists from the Plains to the East Coast. A stable low-level airmass will continue to overspread most of the CONUS, limiting thunderstorm development. Nonetheless, the approach of the aforementioned upper trough may promote enough cooling aloft (and associated scant buoyancy), amid deep-layer ascent, to promote the development of a few low-topped storms. Isolated lightning flashes may accompany the stronger updrafts along the CA/OR coastline. ..Squitieri.. 11/05/2025
